| 摘 要： | 在高速衰落多径信道中，传统的Ｒａｋｅ接收机的性能会大大降低。本文基于自子波变换和时间、尺度分辨率的概念，从理论和仿真实验两方面对信道建模和时间／尺度Ｒａｋｅ接收机进行了分析，并与传统的Ｒａｋｅ接收机进行了比较，结果表明时间／尺度联合分集能有效地克服高速衰落多径信道的影响。

| Abstract: | s:The RAKE receiver performance is significantly degraded in communication over fast fading multipath channels Based on AWT and time and scale resolution of a signal,this paper,via theoretical analysis and computer simulation,explores channel modeling and the performance of the time scale RAKE receiver,and makes contrast with traditional Rake receiver The simulation results indicate that it can work better than traditional Rake receiver in fast fading multi path channels |

| Keywords: | fast-fading multipath channels auto wavelet transform(AWT) time scale Rake receiver |
